Drip Irrigation

Filters and Pressure Regulators

Filters are used to protect drip emitters, dripperline, sprayers, bubblers and misters from sand, silt and other impurities that may clog them over time. Filters are typically installed between the vacuum breaker and pressure regulator. Proper water filtration is essential for the efficient operation of drip irrigation systems. Filters have a maximum flow rate capacity so check your flow before sizing the filter.

Filters are available in various configurations including Y-Filters (also know as a Wye-filters), inline filters and tee filters. Most filters have removable and replaceable screens (either polyester or stainless steel) that come with 120 or 150 mesh. The mesh size indicates the degree of filtration with the higher the number the finer the degree of filtration. Most household water source connections will need either a 120 or 150 mesh filters. Filters are not designed to operate under static pressure and must be installed after any valves, timers or faucets to operate properly. Filter connectors are available with both pipe and hose thread connections. Periodic cleaning of the filter is recommended.

Pressure regulators control the pressure of the system. Most drip or micro-spray system operate in the 20 to 30 psi range. They are available in both hose or pipe thread connections. Pressure regulators are installed downstream of the filter and the valve and are not designed to operate under static pressure.

A compact combination pressure regulating filter is also available.

For those that prefer a kit form, a drip zone package including the regulator, filter and fittings is available.
